The Scorpion Clan historical archives contain three different versions of the sorcerer Iuchiban's deadly legacy; any or none of them may be correct. Acting in secret, unknown even from his own followers, Iuchiban had Yajinden forge a quartet of swords, their blades were christened in blood and alloyed with the souls of Rokugan's greatest samurai. Through hellish sacrifices, they were hammered into existence the blades with blood and fire, upon an anvil comprised of an oni's skull covered in flesh, fire, and the molten steel of the Moon's own hatred. This foul stone became known as the Anvil of Despair, and the cries of the souls it has devoured can still be heard on the darkest nights in the Twilight Mountains; its hunger has never been sated.
